ANALOG-TO-DIGITAL CONVERTER

摘要

The auto-ranging measuring instrument with multi-decade read-out is suitable for use with input variables having non-linear characteristics. The input transducer signal passes to a series of threshold detectors and to one input of a compensation amplifier. The detector outputs are encoded so that the input signal range is assigned to a decade and the decimal point determined and correctly displayed. The output of the encoder also controls a log/lin converter so that linearization is applied only to the pertinent signal range. The put of the converter is connected to an analogue/digital converter and the output of this is used to drive a six-digit, suppressed-zero display.
